Yes
RB (not BB) natively supports as many ins/outs as your system can list.

I've run multiple cards, each with 8 in/out, to get 16 in/out total more than once.
Mind you these cards could be sync'd to avoid drifting, but a single device with 8 in/out is used quite regularly here in RB and PT.

The OP stated in his post it was RB and PT (not BB).

I suspect the manufacturers driver is not properly installed so windows can see it.
